Shingo Okazaki is a young man devoted to his mother to a degree that’s rare in Japan. He’s a young fellow who treats his mother with respect, but his tendency to overdo it makes his filial devotion look more like a little fault to those around him. Then, a young woman falls in love with him. She finds it very admirable that he takes such good care of his mother, but is also a bit confused by this fellow who seems to care more for his mother than for his girlfriend.
